A 3450 RPM single phase motor will run at 3599 RPM with no load, and drop down to 3450 RPM as the load increases. That's in the US where we have 60 Hz power. The oil pumps I'm familiar with all run at half engine speed, so your pump thinks it's on an engine running 7000 RPM. It certainly ought to be doing something at that speed.

Was it primed when you ran it with the motor? You know it was primed when you ran it with the drill, so did you try running it on the motor after you ran it with the drill?
06 Canyon: The vacuum gauge plus wheel covers helped increase summer 2015 mileage to 38.5 MPG, while summer 2016 mileage was 38.6 MPG without the wheel covers. Drove 33,021 miles 2016-2018 at 35.00 MPG.

22 Maverick: Summer 2022 burned 62.74 gallons in 3145.1 miles for 50.1 MPG.
